SUMNER, a the top of which the double-way trolley-track citizen of the United States, residing at Hol- Ois secured in a horizontal position in any yoke, in the county of I-Iampden and State of suitable manner, said trolley-track consisting 5 5 Massachusetts, have invented new and useful of a tube substantially of a rectangular cross- Improvements in Trolley-Hangers for Doors, section at its upper portion and having the of which the following is a specification. lower edges curved in toward the median line This invention relates toimprovemeuts in and then turned upward, so that the bottom sliding doors which are suspended through of the tube has a trough a at each side of a 0o [0 trolley carriers and hangers from a trolleylongitudinal central opening b.v

While the transverse aperture J, having a contracted opening leading to the top edge of the door open at one side of the door and having a closing wall at the other side, may readily be formed in various manners as deemed expedient by a mechanic, I have, as a preferable means for attaining the construction, employed a bushing G, which consistsof a plate as to form the closing end wall, (in which the hole r is formed,) and to lie against and be screwed to the side of the door and having integrally therewith a laterally-extended U shaped socket-casin g at the upper inner edges of which the ledges 0 0 are formed, and said U shaped part is let into a corresponding depression formed within the top edge of the door.

What I claim as my invention is 1. In combination, the trolley-track, rollercarriers supported thereon, and ahanger supported from said roller-carriers, comprising suspension-posts having terminal enlargements, and the door formed or equipped at its upper portion with transversely-extending apertures and contracted openings lead ing therefrom to the top of the door, and in which apertures said post enlargements are entered for engagement, and an operatingsorew applied for securing a movement of sand door laterally with relation to said suspension-posts, substantially as set forth.

2; The trolleytrack comprising double ways a a, roller-carriers, each consisting of a pair of separated rollers and a uniting-axle, a hanger consisting of a longitudinal bar h and ,posts j, each provided with the enlargement 70, having the transverse screw-threaded opening 'rh therein, combined with the door provided with the bushings, each consisting of the plate w, having the transverse hole r, and having the aperture provided at its upper end with the ledges 0 0, and with which sockets the post enlargements fit for engagement, and the operating-screws F, substantially as described.
